Genera In Family: +- 800 genera, +- 25000 species: especially tropics (worldwide except Antarctica). Many cultivated for ornamental, especially Cattleya, Cymbidium, Epidendrum, Oncidium, Paphiopedilum; Vanilla planifolia Andrews fruits used to flavor food. Note: Platanthera may be paraphyletic without inclusion of Piperia (Bateman et al. 2009 Ann Bot 104:431--445); study needed.
